You're on the right track. If you know about the FS variable, do you know about the RS?
Code:
 awk 'BEGIN { RS="[<>]";FS="\"" } /^a href/ { print $2 }'  | sort | uniq -c

Will give you a list of each href in the file, and the number of times it appears in the file.

PS: Older awks won't handle the \" code above. If on Sun, you'll need mawk, nawk, or gawk.
